8 Claims

1. An aluminum alloy conductive wire, comprising:

0.15 mass % or more and 0.25 mass % or less of Si,

0.60 mass % or more and 0.90 mass % or less of Fe,

0.05 mass % or more and 0.15 mass % or less of Cu,

0.46 mass % or more and 2.70 mass % or less of Mg, and

0.03 mass % or less in total of Ti, V, and B,

wherein the aluminum alloy conductive wire has tensile strength of equal to or less than Ti MPa represented by formula (1) below and conductivity of equal to or more than C % IACS represented by formula (2) below in a case where a content rate of Mg in the aluminum alloy conductive wire is x mass %,
